Description
The Orion SpaceProbe 3 Altazimuth Reflector Telescope is highly portable and uncomplicated scope, great for all-around astronomical observing. SpaceProbe 3 reflector telescope makes the night sky's treasures accessible right from the backyard. It reveals Saturn's picturesque rings, Jupiter's moons and the incredibly cratered terrain of the Moon's surface. It's 3"-diameter (76mm) primary mirror also gathers enough light to snare the faint glows of some very exotic star clusters and nebulas.
The aluminum Newtonian optical tube features a 1.25" rack-and-pinion focuser to ensure sharp images in the eyepiece. Speaking of which, each scope now comes with two interchangeable Explorer II eyepieces (1.25")-25mm (28x) and 10mm (70x)-as well as a wide-field, EZ Finder II to aid in locating objects. An adjustable-height tripod with accessory tray and aluminum legs is also included standard. The SpaceProbe 3 Altaz comes with an Altazimuth mount. The altazimuth mount is lightweight and easy to use with simple up/down left/right motions. |
